## Overview

A flaw was found in GitPython. An incomplete denylist in the `unsafe_git_revision_options` guard omits `--contents` and `-S` options. This allows an attacker to read arbitrary files by passing these options to the `Repo.blame()` function. This can lead to information disclosure, as attackers can supply revision values like `--contents=/etc/passwd` to leak file contents.
